Gilberto has called on Arsenal to learn from arch rivals Manchester United following their Old Trafford tonking.

United bounced back from their dismal derby defeat to Manchester City to demolish Arsenal with a scintillating performance.

And the Brazilian claims the Gunners must show the same resolve to keep their title and Champions League bids on track.

"Of course we can bounce back from this," said Gilberto. "If you look at United, they had a bad result against Manchester City, a big disappointment to them, and they came back very strong in this game against us.

"It's the same for us. We will come back even stronger, starting in the Champions League against Milan on Wednesday, because we don't want to let the opportunities pass us by this season. We must bounce back if we want to achieve something. This group is ambitious to win trophies this season.

"The FA Cup is very important and we're disappointed to be knocked out, but we need to look forward to the game against Milan.

"It is also important that we focus on our position in the league, where we are five points clear, a situation very much in our favour. We must learn from our mistakes and not let a performance like this happen again."

Gilberto claims the thumping has not dented Arsenal's self-belief, but he admits they cannot afford to be so poor again.

Arsenal simply didn't turn up and Gilberto added: "It was very disappointing, especially the way we played in the first half. We didn't play our best and we are very conscious of that.

"We have to realise where we went wrong and make sure we don't repeat it in our next game.

"We simply didn't play our best football. United were up for it and they showed that right from the start and for the 90 minutes.

"For our next game against Milan it is important we change the situation we find ourselves in at this moment. We must concentrate on Milan and try to put this result behind us."

Gilberto also had a warning for Nani and claims the Manchester United winger could get seriously injured if he carries on showboating.

Gilberto stepped in to act as peacemaker when William Gallas kicked the Portuguese star in frustration for trying to humiliate him and says his antics could land him in trouble.

"I just spoke to him and told him it wasn't necessary for him to do that," he said. "I told him he could get a bad kick doing that. But I don't think any of our players would kick him too hard.

"In these situations I do my best to calm down my team-mates because we need all of them on the pitch to fight for the team.
